DATA SHEET MOS INTEGRATED CIRCUIT µPD4382161, 4382181, 4382321, 4382361 8M-BIT CMOS SYNCHRONOUS FAST SRAM FLOW THROUGH OPERATION Description The µPD4382161 is a 524,288-word by 16-bit, the µPD4382181 is a 524,288-word by 18-bit, the µPD4382321 is a 262,144-word by 32-bit and the µPD4382361 is a 262,144-word by 36-bit synchronous static RAM fabricated with advanced CMOS technology using N-channel four-transistor memory cell. The µPD4382161, µPD4382181, µPD4382321 and µPD4382361 integrate unique synchronous peripheral circuitry, 2-bit burst counter and output buffer as well as SRAM core. All input registers are controlled by a positive edge of the single clock input (CLK). The µPD4382161, µPD4382181, µPD4382321 and µPD4382361 are suitable for applications which require synchronous operation, high speed, low voltage, high density and wide bit configuration, such as cache and buffer memory. ZZ has to be set LOW at the normal operation. When ZZ is set HIGH, the SRAM enters Power Down State (“Sleep”). In the “Sleep” state, the SRAM internal state is preserved. When ZZ is set LOW again, the SRAM resumes normal operation. The µPD4382161, µPD4382181, µPD4382321 and µPD4382361 are packaged in 100-pin plastic LQFP with a 1.4 mm package thickness for high density and low capacitive loading. Features • Single 3.3 V power supply • Synchronous operation • Internally self-timed write control • Burst read / write : Interleaved burst and linear burst sequence • Fully registered inputs for flow through operation • All registers triggered off positive clock edge • LVTTL Compatible : All inputs and outputs • Fast clock access time : 8.5 ns (100 MHz), 9 ns (90 MHz) (µPD4382321, µPD4382361) ★ 9 ns (90 MHz), 10 ns (83 MHz) (µPD4382161, µPD4382181) • Asynchronous output enable : /G • Burst sequence selectable : MODE • Sleep mode : ZZ (ZZ = Open or Low : Normal operation) • Separate byte write enable : /BW1 - /BW4 (µPD4382321, µPD4382361), /BW1 - /BW2 (µPD4382161, µPD4382181), /BWE Global write enable : /GW • Three chip enables for easy depth expansion • Common I/O using three state outputs The information in this document is subject to change without notice.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.

No license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC or others. • Descriptions of circuits, software and other related information in this document are provided for illustrative purposes in semiconductor product operation and application examples. The incorporation of these circuits, software and information in the design of customer's equipment shall be done under the full responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third parties arising from the use of these circuits, software and information. • While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize risks of damage to property or injury (including death) to persons arising from defects in NEC semiconductor products, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment, and anti-failure features. • NEC semiconductor products are classified into the following three quality grades: "Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products developed based on a customer-designated "quality assurance program" for a specific application. The recommended applications of a semiconductor product depend on its quality grade, as indicated below. Customers must check the quality grade of each semiconductor product before using it in a particular application. "Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness to support a given application. (Note) (1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries. (2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for NEC (as defined above). M8E 00. 4
